With reference to 'Near Field Communication (NFC) Technology', which of the following statements is/are correct?
1. It is a contactless communication technology that uses electromagnetic radio fields.
2. NFC is designed for use by devices which can be at a distance of even a metre from each other.
3. NFC can use encryption when sending sensitive information.
Select the correct answer using the codes given below.
-
A.
1 and 2 only
-
B.
3 only
-
C.
1 and 3 only
-
D.
1, 2 and 3
Correct Answer:
C. 1 and 3 only
Explanation:
The correct evaluation of the statements about Near Field Communication (NFC) technology is:
NFC is indeed a contactless communication technology that uses electromagnetic radio fields to enable data transfer between devices in close proximity. This is correct.
NFC is designed for very short-range communication, typically within 4 cm or less, and not for distances as large as a meter. So, statement 2 is incorrect.
NFC can use encryption when sending sensitive information, allowing secure communication for applications like payment systems and data transfer. This is correct.
Therefore, the correct answer is (c) 1 and 3 only.
